Hi, Maddocks.
You did get the idea.
Dräger tubes can be used for estimates, however I don't know how it reacts in H2S stripper top gases.
In the catalog is not clear how the concentration of the species interfere (H2S and NH3) in the result.
It's said that the indication is not affected by 2000 ppm of H2S and SOx, but the H2S level will be much higher.
The other point is that we wish to have a lab procedure in order to do the analysis in regular basis, say once or twice a month.
Sulphur Experts has a proprietary method. I'd like to know if is there an standard method, besides that one.
